Dave - Do you have an online link somewhere that explains this concept? I'd be interested in reading more.
I have 2 small ponds that are loaded with minnows. I scoop the water out every so often and pour it over my garden beds. The plants really perk up when I do that! And then I add clean well water to the ponds as I don't use a filtering system, just waterlilies to help clean the water. I might be interested in the aquaponics that you are doing.
